  • Visual Tracking Modalities for a Companion Robot

    This article presents the development of a human-robot interaction mechanism based on vision. The functionalities required for such mechanism range from user detection and recognition, to gesture tracking. Particle filters, which are extensively described in the literature, are well suited to this context as they enable a straight combination of several visual cues like colour, shape or motion. Additionally, different algorithms can be considered for a better handling of the particles depending of the context. This article presents the visual functionalities developed namely user recognition and following, and 3D gestures tracking. The challenge is to find which algorithms and visual cues fulfil the best, the requirements of the considered functionalities for our companion robot. The employed methods to attain these required functionalities and their results are presented

  • Neck localization and geometry quantification of intracranial aneurysms

    We present an approach for accurate localization of the neck of intracranial aneurysms and quantification of their geometry that is useful for their treatment through endovascular embolization. In particular, we first obtain a vessel segmentation using a topology-preserving level set method and extract the surface of the segmented vessel. We then separate the aneurysm from the parent vessels and localize its neck by formulating the aneurysm segmentation problem as an s-t minimum cut problem. Finally, we estimate clinically relevant geometric parameters of the aneurysm. The results indicate that there is good agreement between the measurements obtained by the proposed approach and two independent manual sets of measurements obtained by two experienced interventional neuroradiologists.

  • Neural networks for convex hull computation

    Computing convex hull is one of the central problems in various applications of computational geometry. In this paper, a convex hull computing neural network (CHCNN) is developed to solve the related problems in the N-dimensional spaces. The algorithm is based on a two-layered neural network, topologically similar to ART, with a newly developed adaptive training strategy called excited learning. The CHCNN provides a parallel online and real-time processing of data which, after training, yields two closely related approximations, one from within and one from outside, of the desired convex hull. It is shown that accuracy of the approximate convex hulls obtained is around O[K/sup -1/(N-1/)], where K is the number of neurons in the output layer of the CHCNN. When K is taken to be sufficiently large, the CHCNN can generate any accurate approximate convex hull. We also show that an upper bound exists such that the CHCNN will yield the precise convex hull when K is larger than or equal to this bound. A series of simulations and applications is provided to demonstrate the feasibility, effectiveness, and high efficiency of the proposed algorithm.

  • Combinatorial constructions of low-density parity check codes for iterative decoding

    We introduce a combinatorial construction of regular low-density parity check (LDPC) codes based on balanced incomplete block designs, or more specifically on cyclic difference families of Abelian groups and affine geometries. Several constructions are presented, and the bounds on minimal distance are derived by using the concept of Pasch configurations.

  • Velocity analysis of tri-axial differential pipeline robot when getting across elbow

    A wheel-type pipeline robot applying a tri-axial differential mechanism is presented in this paper, which is targeted for moving inside the elbow while the ratios of angular velocities of the driving wheels depend on their movement trajectories. The main features of the robot are illustrated and some details about the mechanism are provided. To confirm the differential effectiveness of the robot, a geometry model of the robot in the elbow is established, which makes it possible to calculate the wheel centers and the contact points between the wheels and the inner surface of the pipeline. On the basis of the geometry model, the velocity ratios of the driving wheels can be computed. Several virtual experiments are performed, and the differential function of the robot is validated through the comparisons of the results between the theoretical analysis and the experiments.
